@kerry-Cho
@delzac Thanks bro. Fina
I finally found a good example of CNTK image segmentation.
I do not know why I do not include this in the tutorial.
Many people do not know if good examples exist.
Did not I know it alone?

Hi, I understand that 2.7 is the last release.. What does that mean. As far as i understand it works in C# for both training deep neural networks and recalling from them. However the documentation and examples in C# seem incomplete. Furthermore since it is the last release no further major release will be made . Is that a correct summary of the current and final state of affairs?
delzac
@delzac
@Gregor959 Python APIs and related work are complete. C# is more patchy, but still better than anything out there (compared to other frameworks)
Gregor
@Gregor959
@delzac .. there are many deeplearning libraries ( Tensorflow, keras) using python and also more popular ones and ones that are still getting supported with future development. As far as C# and F# are concerned this was the only officially supported library on .net . The .net community has been waiting 5 years for microsoft to get the deep learning on .net . We have existing projects on .net that are screaming for deeplearning... Will the c# interface and examples be completed under 2.7 ? How is the F# looking: 100% complete as pythons's , including the documentation?

@delzac
@Gregor959 For more C# examples, you can check out https://github.com/anastasios-stamoulis/deep-learning-with-csharp-and-cntk

@Gregor959 I'm also wondering about the "last main release" notice for version 2.7. Does anybody know if MS has abandoned CNTK? I've spent months developing a project using CNTK and now I feel like I should start over with a different AI toolkit. So far, I've had no luck trying to find out from MS. At this point, I think it would be a waste of time to put any time on learning any thing new for CNTK.
willprgm
@willprgm
Does anyone know anything about the fate of CNTK? Has MS abandoned it?
delzac
@delzac
@willprgm you can check out Microsoft/CNTK#3646 on the way forward

@maxima120
I have joined to ask the same question.. @willprgm
"The CNTK 2.7 release has full support for ONNX 1.4.1, and we encourage those seeking to operationalize their CNTK models to take advantage of ONNX and the ONNX Runtime." - I fail to understand relation between CNTK future and ONNX. I thought ONNX is just model export/import format..

@maxima120
Amazon should take over. Anyone knows Bezos phone number?
duxianghong
@duxianghong
in the future, MS will publish the CNTK 3....?
so the CNTK 2.7 is the last main release. right?
delzac
@delzac
Yes cntk2.7 will be the last main release. More details pleases check out here #3646
Hello
@ebarsoumMS
Yes, 2.7 is the latest release.

Hi! I'm training my own data with complex objects:

python 3.5
CNTK 2.6
no GPUs
epoch=20
C.CNTK.TRAIN_E2E = True C.CNTK.E2E_MAX_EPOCHS = 20
C.NUM_ROI_PROPOSALS = 2000 C.DATA.NUM_TRAIN_IMAGES = 39
C.DATA.NUM_TEST_IMAGES = 7 C.DATA.PROPOSAL_LAYER_SCALES = [4, 8, 12]
...
So, I'm getting such outputs, is it normal or does it mea a error?

@TchuBotin Sounds like you need to update your GPU driver

@TchuBotin

Thx @delzac, but I don't have GPU only CPU:

Perhaps, my problem is that the first time I'm trying CNTK.

Hi guys, I created a python package a couple of days back which helps generate ML code based a yml like file called "mlm". This package as of now supports keras and a little of tf2. I would really appreciate if you guys could help out with the CNTK part as well.
Thank you

Hi all. We've been using CNTK with Cuda Toolkit v10.0 and cuDNN v7.5.1. I just tried CNTK with the latest releases of the CUDA Toolkit and cuDNN library for Cuda 10.2. CNTK works fine with these but I was expecting I might see a performance improvement during training given some of NVidia's claims. However, benchmark scores during training are unchanged. Any thoughts here? Was my expectation unreasonable? Just wondering what I'm not getting. (The testing was done on a GTX 1080. I have a newer (but smaller) Quadro T2000 in my laptop that I haven't upgraded for CUDA 10.2 yet. Any reason to expect I'd see an improvement with a different GPU?)

Many thanks.

Hi I am looking for an AI solution that can automatically read data from excel, add conditional logic to excel data currently being added to manually to excel and then finally load data into MS Access . Can I use CNTK to deliver this solution ?
delzac
@delzac
@ambarchakrabarty-DnA No cntk is a deep learning framework and doesn't deal with excel. You might want to try PyXLL

@delzac many thanks for getting back . Sure, I will have a look. Thanks !

Hi, can someone help me understand why CNTK is not getting further releases? There is nothing else that can compete when it comes to C# development.
What should C# developers use instead? Tensorflow.Net is not as C# friendly, and won't work at all with a GTX 760

Will CNTK be participating as an org in Google Summer of Code 2020 by any chance?

Can I use rpc, MPI_send, MPI_recev with CNTK? where I can find basic example distributed CPU with CNTK?
Thanks

Hi All
I am tying to install cntk on my windows 10 machine
by pip install cntk
but it is giving error
ERROR: Could not find a version that satisfies the requirement cntk (from versions: none)
ERROR: No matching distribution found for cntk
how to fix this

@delzac
@DhirajK32398669_twitter What version of python are you using?

Hello, any guys here?
I use PIP to install CNTK on WIN10 1909/1903. But when I run a script, although there is no error message, the training process does not start.
My PC is AMD 3950x + 2080TI.

@Neteraxe
Is it the support of python 3.8.3 available?

@Neteraxe No ther's no support for python 3.8 only up to python 3.6

Is there any interest to support Clang, for Windows builds?
I was thinking about clang-cl , for the C++ code (P/Invoke related) - and OpenCL, GPGPU code could be compiled by existing Clang (11.0 RC2)
